MOTOR FLYING-MACHINE.

Specification of Letters Patent.

Patented May 31, 1910.

Application filed August 27, 1909. Serial No. 514,867.

following to be a full, clear, and exact descri tion of the same.

y present invention relates to motor flying machines of the kinddescribed in my prior application Serial No. 412,859 filed Jan. 27th,1908 and has for its object to provide certain new and improved devicesfor controlling the discharge of compressed air. from the compressionchambers which are closed on top and open at the bottom and the rearend, for the purpose of imparting ascending and forward movements asdesired to the machine without stopping or checking in any way themovements of the rotating devices (wings, screws or the like), whichdraw air from the chambers which are open on top and closed at thebottom and compress it in the chambers which are closed on top and openat the bottom.

I will now roceed to describe the invention with re erence to theaccompanying drawings, wherein:

Figure 1' shows a vertical longitudinal section through a compressionchamber, the bottom of which is completely closed by the air-dischargecontrolling devices, while the rear end is open. Fig. 2 is a similarview showing the bottom of the compression chamber completely open andthe rear thereof closed. Fig. 3 is a diagrammatical cross-sectionthrough suction and compression chambers with rotatory wings and Fig. 4shows a similar section, with a screw in each side opening of thecompression chamber.

My motor flying shi or machine is composed of a plurality of uxtaposedlongitudi nal chambers 1 and 2, as described in speci= flcation SerialNo. 412,859, the chambers 1 being 0 en on top and closed at the bottom,while 0 ambers 2 are closed on to and open at the bottom and rear end.Sai chambers communicate with each other by means of lateral apertures3, in each of which is arra ed to rotate a suitable air-screw 4 (as a sustitute for the rotating wings 1' shown in Fi 3 and described inspecification Serial o. 412,859), carried by the transverse shaft 5. Thevarious shafts 5 are actuated by means of belts, chains or the like 6,passing around a common pulley 7, driven in any suitable way by a motor.The upper part of the air-ship, motor and motor appliances arepreferably arranged on and supported by a suitable framework 8,preferably provided with a platform or platforms for the pilot andpassengers. However this part of the machine does not form a part of mypresent invention.

The compression chambers 2, shown in longitudinal section in Figs. 1 and2 are closed on top and the front and open at the bottom and the rearend as shown. The front portion of the bottom is preferably formed of anincline 9 serving to lessen the resistance to flight.

Journaled at the bottom of the compression chambers 2 are transverseshafts .10, each of which carries a flap 11 adapted to be adjusted andheld in any desired position,

either for closing the bottom (Fig. 1) or partly or completely openingthe same (Fig. 2). -At the rear of the compression chambers arejournaled transverse shafts 12, each of which carries a flap 13, adaptedto be adjusted and held in any desired position either for partly orcompletely opening {Fig 1) the rear end or closing the same Fig. 2).

The transverse shafts l0 and 12 are provided Wit-h levers 14: and 15.respectively,

and these levers are preferablyg connected to each other by suitablemeans 16, so that the bottom flaps 11 are closed when the rear flaps 13are opened and vice versa. Said flaps may be adjusted in the desiredposition by means of hand-wheel 17, connected by means of a chain or thelike 18 to a pulley or chain-wheel 19 arranged on one-of the transverseshafts 10.

The .devices described operate as follows :By the rotation of theair-screws 4 (Fig. 4.) air is drawn from the chambers 1 through theapertures 3 and compressed in the chambers 2, the bottom and rear flapsof the latter being closed. Now if the bottom flaps 11 are opened byturning the handwheel 17 the compressed air escapes downwardly from thechambers 2, whereby a correspondin reaction is produced on the top wall20 0 said chambers (see arrows 21 in respondingly, so that thecompressed air is allowed to escape obliquely and downwardly through thebottom and rear end, a corresponding oblique reaction being therebyproduced on the front and top Walls of the chambers 2, so that theair-ship is raised in an oblique direction. lVhen the bottom flaps 11are completely closed and the rear flaps 13 completely opened, thecompressed air escapes only rearwardly (Fig. 2) and produces acorresponding reaction on the front wall 22 (see arrows 23 Fig. 1) ofthe chambers'2 for the straight flight of the machine; the sustentationof the latter is then secured by the incline t) and the surface formedof the closed bottom flaps 11, both gliding on the atmospheric air.

It is manifest that other suitable devices may be substituted for theflaps 11 and 13 to control the discharge of compressed air from thechambers 2 of the air-ship, Without departing from the scope of theinvention.

Having fully described my invention, What I claim and desire to secureby Letters Patent is 1. In an air-ship of the kind described, thecombination With a frame structure divided into parallel alternatelydisposed suction and pressure chambers, and means disposed in saidpressure chambers for Withdrawing air from saidsuction chambers andcompressing the same in the pressure chambers, of suitable controllingdevices at the open bottom and the rear end of the pressure chamberscapable of. controlling the discharge of air from the latter, and meansfor adjusting said controlling devices as desired, substantially as setforth.

2. In an air-ship of the kind described, the combination With a framestructure divided into parallel alternately disposed suction andpressure chambers, and means disposed in said pressure chambers forWithdrawing air from said suction chambers and compressing the same inthe pressure chambers, of adjustable flaps arranged at the open bottomof the pressure chambers, similar flaps arranged at the open rear end ofthe latter, suitable means for connecting all the flaps so that thebottom flaps are closed When the rear flaps are opened and Vice.

versa, and means for adjusting the flaps as desired, substantially asset forth.

3. In an air-ship of the kind described,

the combination With a frame structure divided into parallel alternatelydisposed suction and pressure chambers, lateral apertures forming aconnection between the latter, and a rotatory air-screw in eachaperture, of suitable controlling devices at the open bottom and therear end of the pressure chambers, capable of controlling the dischargeof air from the latter, and means for adjusting said controlling devicesas desired, substantially as set forth.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing Witnesses.
